Preheat the oven to 400°

Divide melted oil between 4 muffin cups brushing the oil up and around the sides of each cup.

Line each muffin cup with a slice of ham then crack an egg into each ham-lined cup. Season with salt and pepper.

Bake 15 minutes for soft yokes (a little less if you like your yokes runny and a bit more if you want them hard).

Remove from oven and cool for a minute. Remove from tins being careful and serve immediately
